If the same sea area can generate electricity from both wind and solar with almost no need to build a new transmission system, are billion-dollar traditional energy projects at risk of being replaced faster than expected?
On June 12, 2026, information from the feasibility study conducted by Ørsted is attracting great attention from the global energy industry. Denmark is considering deploying floating solar panels just inside the Horns Rev 3 offshore wind farm site, about 40 km off the west coast.
The idea seems simple but can create a revolution in the efficiency of renewable energy investment at sea.
For many years, offshore solar power has been considered too expensive due to the need to build underground cables, transformer stations and its own maintenance fleet. However, Denmark is completely changing this economic problem by taking advantage of the existing wind power infrastructure.
☀️ When it's sunny and there's little wind, solar power reaches high capacity
️ When it's windy andWith little sunshine, wind turbines operate strongly
⚡ The transmission system is used more efficiently throughout the year
This is considered the first offshore hybrid energy model capable of achieving financial efficiency on a large scale.
What is Horns Rev 3
Horns Rev 3 is one of Denmark's largest offshore wind power projects developed by Ørsted.
Parameter Value
North Sea location
Distance to shore 40 km
Investor Ørsted
Country Denmark
New model Wind power combined with floating solar power
Why Costs Can Be Drastically Reduced
The biggest cost of offshore solar power often lies in the infrastructure.
Category Individual Project Hybrid Model
Underground transmission cable New construction Shared use
Offshore transformer station New construction Shared use
Maintenance vessel Private charter Shared use
Separate Integrated Operations Team
Investment costs Very High Significantly reduced
According to the Danish Energy Agency's assessment, sharing infrastructure can help eliminate a large part of initial investment costs, which is the biggest barrier to offshore solar power.
Notable Technical Advantages
Floating solar panels will be installed between rows of wind turbines.
This brings many benefits
✅ The area between the turbines has lower waves
✅ Mooring system can take advantage of infrastructureavailable
✅ Reduce marine survey costs
✅ Easy access for maintenance
✅ No need to expand the beach use area
A special feature is the offshore transformer station which was designed for the time when wind power peaked. On days with little wind but strong sunshine, this spare capacity can be used for solar power without needing to build large infrastructure.
Compare Power Efficiency
Weather conditions Wind power Solar power
Strong sunshine, little wind Low High
Lots of wind, cloudy sky High Low
Mixed weather Moderate Moderate
Combining two sources More stable More stable
This is the reason why many experts believe that the hybrid model can increase the transmission infrastructure utilization ratio to a significantly higher level than each power source operating independently.
The Offshore Energy Race Is Changing
While many countries focus on expanding individual wind or solar power, Denmark is moving towards an integrated model.
Large energy corporations such as Ørsted, Equinor, RWE and Shell are all researching solutions to combine multiple renewable energy sources in the same ocean area to reduce costs and increase operational efficiency.
If the test at Horns Rev 3 is successful, this model can be replicated in the North Seac, Europe and many Asian markets in the coming decade.
Denmark's story shows that the future of energy lies not only in generating more electricity, but also in the ability to maximize the exploitation of every square meter of invested infrastructure. Offshore wind power combined with floating solar power can become one of the most efficient energy models in the world in the period 2030–2040.
